SIMULATION OF THE COALESCENCE PROCESS OF METAL NANOPARTICLES OF DIFFERENT SHAPES

Abstract

The simulation of the coalescence process of gold and copper nanoparticles of different shapes by Monte-Carlo method was carried out. The interaction between nanoparticles was described by many-body Gupta potential. It was found that the shape of nanoparticles significantly affects the melting point and the coalescence process. Moreover, the coalescence doesn't happen at all at certain distances between nanoparticles of an initial configuration.
